Any case of "if" statement is available now.  Approximately equal operator is available now (see Options dialog to set the accuracy):

Hi Andrey,
I see the "Approximately equal" operator accuracy varies from 0 to 15. What does this value actually represent? |

It is an accuracy of the "Approximately equal" operator. F.e. if the accuracy is 0, then pi≈3, if 1, then pi≈3.1, if accuracy is set as 2, then pi≈3.14 etc. Best regards.

Hi Andrey,
considering that the "accuracy operator" parameter that regulates "approximately equal" is unique, wouldn't it be appropriate that it is defined in percentage terms?

It's more than just the decimal place precision.   approximately.sm (5kb) downloaded 14 time(s). |

Best regards. This is a nice new feature. Would it be possible to modify this value independent to regions? Adding another submenu to region right-click would be awesome. As in decimal places, exponential threshold, rounding choosing. Regards

Hi. About the new approximately equal operator, another way to introduce it could be introducing a general infix operator, like in Mathcad. This screen capture is from Mathcad 6 running in Windows 3.11:  For work with units you just need to modify the rhs by abs( a-b ) < UnitsOf( a-b )*TOL (or maybe UoM). Notice that also can be a solution for another features requests, like this one about inline division: https://en.smath.com/for...614_Inline-division.aspxAbout the "Defined Integral supports units now" it is a major improvement, and while there will be many worksheets to update, it is a substantial and very welcome improvement. I do think that some kind of special announcement should be made. Also, if you plan to also modify solve and roots to accept drives, you may want to introduce the two improvements together in a future stable beta release. Finally, many thanks to you Andrey and to all the developers who collaborate with the plugins for this excellent program. Best regards. Alvaro. Edited by user 22 June 2022 04:20:57(UTC)

SMath Studio is a great alternative to MathCAD. It is small and portable. I use it primarily for structural engineering calculations and for documenting my work. Many thanks to Andrey and the other developers for this great tool.

 Thank you. But the problem is not because of eval(). She's somewhere deeper. My f3(x) and f4(x) limits are ainterp() of the table data.

The question is why in the stable version integrals are calculated without problems, but in the new one it gives an error in the same places?

It may be the XLS import ? Try NOT import as a stand alone system. It doesn't matter if there is an import from Excel or not. Proizvol'noe sechenie_no XLSX.sm (74kb) downloaded 11 time(s).
